Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing device, and more particularly to a character processing device that can fill in a part of a figure such as a line drawing or a graph with a specific pattern.

[Prior Art] Conventionally, in this type of device, as shown in FIG. 2, several patterns for filling in a part of a line drawing are stored in a fixed storage device such as a character generator or a program, and the user selected the pattern he wanted to use from among the filling patterns.

FIG. 2(A) shows that the position of filling is specified during the creation of a figure, and FIG. 2(C) shows that the portion specified in FIG. 2(B) has been painted with the filling pattern.

In such conventional devices, the type of pattern used to fill in a part of a created figure is fixed for each system, and there is a restriction that only a fixed pattern can be used to fill in the figure. Further, even if a coloring pattern can be registered, the registration requires a complicated procedure.

[Problems to be Solved by the Invention] The purpose of the present invention has been made in view of the above-mentioned drawbacks.
By using part of the shaded characters as a font for output, and also as a fill pattern for any shape, you can create any fill pattern with the simple operation of adding or changing the custom character font. An object of the present invention is to provide a character processing device that can be used.

[Example〕 The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a diagram conceptually explaining the present invention.

The shading pattern used for filling created with the external character pattern creation means in 1-1 is stored in the external character storage means in 1-2 in 1-3.
It is stored together with the custom character code input at stage f of the custom character code input. The figures created using the external character creation method in 1-5 are as follows:
During the creation of the 0 figure stored in the figure storage means of l-6, 1-
The external character code of the paint pattern input from the external character code input stage 3 is incorporated into the figure data, and when displaying or printing the 0 figure stored in the figure storage means 1-6, Recall the corresponding figure data from the figure storage means, read out the font from the f-stage of the external character storage 1-2 through the external character designation means 1-4 based on the external character code of the fill therein, Figures are painted and output in the figure output stage f of 1-7.

The invention shown in FIG. 1 will be further explained.

FIG. 3 shows the configuration of an embodiment of the present invention.

In the configuration shown in FIG. 3, the CPU is a central processing unit in the form of a microprocessor, and performs calculations, logical judgments, etc. for character processing, and connects these buses via address bus AB, control bus CB, and data bus DB. control each component connected to the

Further, recognition of figures to be filled in in line drawings, determination of the size of figure areas, generation of figures, etc. are also performed by this CPU based on the contents of the RAM, which will be described later.

Address bus AB transfers address signals indicating the components to be controlled by the microprocessor CPU. Control bus CB is microprocessor CPU
transfers and supplies control signals for each component to be controlled. The data area DB transfers data between each structure 1& and equipment.

Next, ROM is a read-only fixed memory, and the sixth
As shown in the figure, +l1ri, etc. controlled by the microprocessor CPU, which will be described later, are stored.

Further, the RAM is a random access memory having a structure of 1 word and 16 bits, and is used for temporary storage of various data from each component. The data to be stored includes a data area R1 that determines the size of sentence 1, such as character spacing and line spacing, and an intermediate data area R2 that is used when generating figures.
, a work area R3 for creating external characters, and a pattern area R4 for generated figures.

The KB is a keyboard, including alphanumeric keys, mogana keys, katakana keys, character keys for specifying graphic areas, keys for inputting character symbols, and keys for specifying the start and end of kanji conversion, as well as keys for character processing. It is equipped with various function keys for instructing various functions to the device, and is used for inputting external character patterns, inputting document data, inputting graphic data creation commands, etc.

DBUF is a buffer memory that stores document information etc. input from the keyboard KB.

The DISK is a magnetic disk device that serves as an external storage for created external character patterns and document graphics.

CR is a cursor register, the contents of which can be read and written by the CPU. CRT controller CRT described later
C is the display device C corresponding to the address stored here
RT Display the cursor at the h position.

A CRT is a display device using a cathode ray tube or the like, and a dot-configured display pattern and a cursor display on the display device cRT are controlled by a CRT controller CRTC.

The CRT controller CRTC has a cursor register CR.
and the display bag 22 for displaying the contents stored in the buffer DBUF.
It will be displayed on the CRT.

CG is a character generator, and the display device CRT
Character signals such as characters, symbols, and cursors to be displayed are generated.

The character processing device of the present invention, which is composed of each of these components, operates in response to various human inputs from the keyboard KB, and when an input from the keyboard KB is supplied, an interwoven signal is first generated. central processing bag zcp
The central processing unit CPU reads various control signals stored in the ROM, and various controls are performed in accordance with these control signals.

Note that the four-stage display that displays the contents of the buffer DBUF in accordance with the position on the display device CRT is well known, so its explanation will be omitted. The display will be performed in

Here, in this embodiment, it is assumed that the external character code is divided into two types: normal external characters and shaded external characters, so that there are no common parts. That is, for example, Private character code = 1 to 376: Normal private character code = 5
01-594: Use #1 as a special character, and create a custom character font for each character.

Next, with reference to FIGS. 4 and 5, the operation of filling in figures in the character processing apparatus of the present invention will be explained, taking as an example the case of displaying on a CRT. Note that the methods for inputting documents and figures, and for inputting external character patterns are well known, and therefore their explanations will be omitted.

FIG. 4 shows the designation of a fill pattern when creating and editing figures. In FIG. 4, a indicates an area on the CRT screen for displaying the line drawing being created, and b indicates an area for monitoring input from the keyboard. C
is a cursor for creating line drawings, and indicates a closed figure to be filled. d indicates that the fill pattern is specified by its external character code. Here, as the data for filling the shape, the position of the shape represented by C and d
The external character code for the fill specified in is saved.

FIG. 5 explains the process of filling the figure designated in FIG. 4 with the designated pattern of hatched external characters. Figure 5 (
A) is the data for filling in the figure, C is the position of the cursor at the time when the edge is specified, and d is the filling pattern.

FIG. 5(B) shows that a pattern has been created in the work area by connecting the specified external character patterns until the area becomes larger than the figure specified in FIG. 5(A). FIG. 5(C) is an extracted portion of FIG. 5(B) that fits within the graphic area. FIG. 5CD) shows the pattern of FIG. 5(C) superimposed on the figure of FIG. 5(A).

In step 56-1, a shaded external character code to be used for coloring is input from the keyboard KB. Step 56-2
, the input external character code is R as graphic data along with the cursor position at the time the code was input.
Save to AM5.

In step 56-3, the font of the input external character code is read from the external storage device. What is read here is a pattern that is the size of one character (e.g. 24x24
dot). In step 56-4, a fill pattern is created by connecting fill fonts to the fill work area R3. In step 56-5, unnecessary portions of the pattern in the work area R3 are erased in accordance with the shape of the figure. In step 56-7, the ff created in step 56-5 is
i Return the LJ pattern to the original (4th shape) in area R4.

In the above embodiment, only the filling of figures is handled, but if a filling pattern is used, such as a graph,
The present invention can be applied to all of them. Particularly in the case of graphs, it is rare for a user to even be able to select a coloring pattern, and there are no cases in which a user can create such a pattern, so the effects of the present invention are significant.

[Effects] As is clear from the following explanation, according to the present invention, it is possible to create fill patterns such as line drawings and graphs using the existing external character creation r-stage without using any new functions. A character processing device capable of filling figures with any pattern created in this way was realized.
